FIGURE 4.

(a) Depression prevalence in each hair loss disease shows relatively similar incidence to the control, however this is higher than WHO estimate, which puts depression at 4.5% in healthy individuals. There were no publications associating TE with depression. (b) Anxiety prevalence distribution in hair loss patients and in the general population shows higher levels of anxiety in all hair loss types relative to levels in the general population. (c) The correlation between acute stress and hair loss was only reported in AA and other alopecia patients, not in AGA or cases of TE. (d) The association of several other psychiatric disorders with each hair loss disease suggests highest prevalence in AGA and TE, however in each case this is a single datapoint from one publication. AA, alopecia areata; AGA, androgenetic alopecia; TE, telogen effluvium.
